For most of us a post-silly-season detox means cutting out beers before 12pm and not munching on ham fat, but for Gwyneth Paltrow it equates to an extreme 300 calorie a day detox over 72 'hanger' filled hours.

The almost lovingly out of touch 41-year-old actress has put together a three day detox diet for her lifestyle website Goop with detox specialist Dr Alejandro Jungerthat suggests we don't eat any solids until about 6pm every day, and when we finally get to munch on actual food it's ¼ of a stuffed squash or one skinless chicken breast.

For instance, day two of the diet starts with a glass of water (room temperature, let's not go too crazy) with lemon.

At 8am you're then allowed a cup of herbal tea - woo hoo. At 10am you can sip on a Peppermint hot chocolate crafted from almond milk, stevia, mint flavoured chlorophyll and - wait for it - two tablespoons of raw cacao.

Come 1.30pm you'll get the equivalent of about one carrot blended into a soup, and just as your stomach is about to go loco and begin eating surrounding organs at 4pm you can munch on a handful of mixed seeds (are we birds?).

Your big meal comes at 6pm with, yes, one skinless chicken breast and a few bits of broccoli (at which point we'd be so hungry we'd skip Campbell Live and head straight to bed for the fear that we may try and eat John's face and thus electrocute ourselves on our flatscreen).

This diet is actually far less strict than her previous plans - here's a day from her 2008 detox:

- 7am (or upon rising): Glass of room temperature lemon water

- 8am: Herbal tea

- 10am (breakfast): Blueberry and Almond Smoothie

- 11:30am: Coconut water*

- 1:30pm (lunch): Salad with Carrot and Ginger Dressing

- 4pm (snack): A handful of mixed pumpkin and sunflower seeds

- 6pm (dinner): Broccoli and Arugula Soup

*Make sure that the coconut water has no added sugar. Fresh is ideal but the brands Zico or Vita Coco are readily available.

But still, when 'starvation' diets like the 5:2 suggest someone eats 500 calories a day, and never on consecutive days, 300 calories a day for three days straight seems the opposite of healthy.

Leading New York nutritional medicine expert Dr Fred Pescatore has slammed the diet, telling Radar online:

"The only foods on tap are foods meant to make you eliminate [waste] one way or the other. It is essentially a three-day fast with a bit of protein thrown in... There is no doubt that this will make you lose weight, as this is a starvation-type-diet with lots of liquid to make you feel full, but nothing to nourish the body or soul... It's basically no food or nutrition."
